DOMEN l CO PATRIARCA wlammawm ATTORNEY This invention relates to an automatic humidifier for a cigar case and more particularly to a warning signal operable when the liquid in the container falls below a predetermined level.

One object of the present invention is to provide an automatic humidifier for a cigar case.

Another object of the present invention is to provide a hydraulic float control of the electrical circuit in an automatic humidifier.

Another object of the present invention is to provide a Warning light to indicate that the fluid in the humidifier has fallen below a safe operating level.

And still another object of the present invention is to provide a warning signal, electrically operated, to indicate lack of water in an automatic humidifier.

Other objects of the present invention will be pointed out in part and become apparent in part in the following specification and claim.

In the past, cigar cases have lacked automatic humidification and a warning signal to indicate that the water in the reservoir had dried up, with the consequent lack of humidification and damage to the tobacco products in the display case. The present invention was created to overcome this deficiency, by providing automatic humidi fication and effective automatic control of the humidifier without detracting from the esthetic appearance of the display case and without creating a nuisance.

Referring to the drawings in which similar characters of reference indicate corresponding parts in all the figures:

Figure l is a perspective view of an automatic humidifier for a cigar case having the warning light.

Figure 2 is a bottom plan view of the reservoir cover showing the float, fan and hydrostat housing.

Figure 3 is a detail view, in section, of a louver.

Figure 4 is a plan view of the reservoir cover with its housing removed showing the electric motor for the fan, the control switch for the warning light and some electric wiring.

Figure 5 is a wiring diagram of the electric circuit controlling the warning light.

Figure 6 is a side sectional of Figure 1.

Referring to Figure 1 wherein is illustrated the new and improved automatic humidifier lit for a cigar case with a fluid level control warning light 11. he humidifier it) consists of front and rear walls 12, i3 and left and right sides 14, 15, bottom 16 and cover 17 having vents 50.

Front wall 12 and rear wall 13 are provided with louvers 18, 19, 29 and 2i. Cover 17 has a commercial motor 23 mounted thereon with the motor shaft 24 projecting through the cover and having a propeller 25 secured thereto. A micro-switch 26 is also mounted to cover 17 with View taken along line 65 2,730,340 ?atented Jan. 10, 1956 its plunger 27 projecting through said cover. A bracket 28 is secured to the underside of cover 17 and provides a pivotal mounting 30 for a bell crank lever 31 which engages plunger 27 with one end and has a float 32 pivotally mounted at 33 on its opposite end. A housing 34 provided with air slots 35 encases motor 23, micro-switch 26 and has a commercial hydrostat 36 secured to it. Housing 34 is mounted on cover 17. The fluid level control light ll may be of any commercial manufacture.

Figure 5 depicts the wiring diagram. An electric plug (see also Figure 1) is connected to the source of electric current. A wire 40 connects one side of plug 37 to one side of a connection 41 for warning light 11. A second wire 52 connected to plug 37 along with wire 40 is connected to hydrostat 36. A wire 43 connects hydrostat 36 with motor 23. A wire 44 connects the other side of plug 37 with motor 23. Wire 45 connects plug 37 along with wire 44 to micro-switch 26. Wire 46 connects microswitch 26 with connection 41. The wiring arrangement is such that hydrostat 36 controls the running of motor 23 whenever atmospheric conditions actuate said hydrostat 36. When motor 23 is operating propeller 25 is revolving fanning reservoir 42 formed by bottom 16, front and rear walls l2, l3 and left and right side walls 14, 15. If there is water in reservoir 42 float 32 will be in raised or inactive plunger 27 position. If there is no water in reservoir 42, float 32 will be in lower or active plunger 27 position, thereby actuating micro-switch 26 into closed circuit position, causing warning light 11 to be lit. A buzzer could be used in place of light 11.

Thus it will be seen that adjustment between bell crank lever 31 and plunger 27 will allow float 32 to actuate micro-switch 26 and warning light 11 whenever the water in reservoir 42 falls below a predetermined level.

The water in reservoir 42 may be replaced through any one of the louvers 18, 19, 20 or 21.

Having shown and described a preferred embodiment of the present invention, by way of example, it should be realized that structural changes could be made and other examples given without departing from either the spirit or scope of this invention.

What I claim is:

In a humidifier the combination of a housing adapted to hold a liquid and having a multiple number of louvers, a cover provided with air vents and having a bracket secured thereto, a hydrostat secured to said cover, a micro-switch secured to said cover provided with a plunger extending through said cover and a motor secured to said cover and provided with a shaft extending through said cover, a propeller secured to said shaft, a bell crank lever pivotally mounted in said bracket with one end engaging said plunger, a float pivotally mounted in the other end of said bell crank lever and operable in said case, a warning signal, an electrical circuit uniting said hydrostat, said micro-switch, said motor and said warning signal to cause said motor to be under the electrical control of said hydrostat and said warning signal to be under the electrical control of said micro-switch through the action of said float on said plunger through the medium of said bell crank lever.
